Title: Ground fault detector
Inventor: SATO KAZUYUKI
IPC: G01R31/02
Filed: 1990-09-17
Abstract: PURPOSE:To prevent unnecessary function upon occurrence of ground fault due to an excessive surge such as a lightning surge by a method wherein a synthesizing means synthesizes an output from a ground fault detector and an output lagged behind by a predetermined time and then the level is judged based on thus synthesized output. CONSTITUTION:Ground fault current flowing through an AC path 1 is detected through a ZCT 6 and amplified through an amplifier 20 and then fed to a level judging unit 21 and a delay circuit 25. The level judging unit 21 produces a pulse signal having time width corresponding to the interval of negative level. The delay circuit 25 produces an output lagged by half period behind the output from the amplifier 20. An adder 27 adds the outputs from the amplifier 20 and the delay circuit 25. A retriggerable one-shot circuit 28 generates a pulse signal having time width corresponding to the interval of positive level. An AND gate 31 performs logical operation on both pulse signals and provides the output to the gate electrode of a switching element 8 thus operating a circuit breaker 5 to interrupt the AC path 1.

Title: Acoustic signal formation circuit
Inventor: MATSUDA MITSUHIRO
IPC: G10K15/04
Filed: 1987-09-30
Abstract: PURPOSE: To output both of a chime sound and a tremolo by switching and to reduce the number of parts to reduce the cost by adding a switching circuit or the like which switches a one shot trigger circuit to an oscillation circuit. CONSTITUTION: A multi-circuit is used which can perform switching between the one shot mode and the oscillation mode, where a frequency which is lower than an audible frequency but has a relatively short period is oscillated, in accordance with a second control signal. In the one shot mode, the rise of a first control signal is used as a trigger to generate a pulse having relatively long time width, and amplitude-modulated waves of the signal, which is obtained by differentiating this pulse by a differential circuit having a relatively long period, and an audible frequency signal are obtained; and in the oscillation mode, a square wave signal having a period shorter than that in the one shot mode is generated, and amplitude-modulated waves of this signal and the audible frequency signal are obtained.  Consequently, the multi-circuit is operated as a chime sound generation circuit in the one shot mode and is operated as a tremolo generation circuit in the oscillation mode. Thus, the chime sound and the tremolo can be outputted from one circuit by switching, and the circuit is simplified, and the number of parts and the cost are reduced.
